a heating unit for supplying at least one of hot air and steam into the treating chamber; and a conveying device for conveying clothes positioned outside the cabinet to the inside of the cabinet, wherein the conveying device includes: a frame including at least two sliding surfaces inclined downward in a first direction, and at least two restraining surfaces that is disposed between the two sliding surfaces and defines a surface intersecting the sliding surfaces; a lifter including at least two inclined surfaces inclined downward in the first direction, and at least two intersecting surfaces that is disposed between the two inclined surfaces and defines a surface intersecting the inclined surfaces; and a drive unit which moves the lifter in a vertical direction intersecting the first direction, wherein each of the intersecting surface is disposed on an arbitrary line parallel to each of the sliding surfaces in the vertical direction. ## Claims ### Claim 1 A conveying device comprising: a frame comprising at least two sliding surfaces inclined downward in a first direction, and at least two restraining surfaces that is disposed between the two sliding surfaces and defines a surface intersecting the sliding surfaces; a lifter comprising at least two inclined surfaces inclined downward in the first direction, and at least two intersecting surfaces that is disposed between the two inclined surfaces and defines a surface intersecting the inclined surfaces; and a drive unit which moves the lifter in a vertical direction intersecting the first direction, wherein each of the intersecting surface is disposed on an arbitrary line parallel to each of the sliding surfaces in the vertical direction, wherein the frame comprises: a treating area in which an object to be conveyed is treated, and which comprises one sliding surface and one restraining surface connected to each other; and a preparation area which is positioned before the object to be conveyed is conveyed to the treating area, and which comprises at least two sliding surfaces and at least two restraining surfaces. ### Claim 2 (depends on 1) The conveying device of claim 1, wherein each of the restraining surfaces connects the sliding surfaces adjacent to each other. ### Claim 3 (depends on 2) The conveying device of claim 2, wherein a lower end of each of the restraining surfaces is connected to a lower end of one of the sliding surfaces adjacent to each other, and an upper end of each of the restraining surfaces is connected to an upper end of one of the sliding surfaces adjacent to each other. ### Claim 4 (depends on 1) The conveying device of claim 1, wherein the restraining surface is extended in parallel to the vertical direction. ### Claim 5 (depends on 1) The conveying device of claim 1, wherein an inclination angle of the sliding surface with respect to the first direction ranges from 20° to 70°. ### Claim 6 (depends on 1) The conveying device of claim 1, wherein each of the sliding surfaces is disposed not to be overlapped with each other in the vertical direction. ### Claim 7 (depends on 1) The conveying device of claim 1, wherein each of the intersecting surfaces connects the inclined surfaces adjacent to each other. ### Claim 8 (depends on 7) The conveying device of claim 7, wherein a lower end of each of the intersecting surfaces is connected to a lower end of one of the inclined surfaces adjacent to each other, and an upper end of the intersecting surfaces is connected to an upper end of one of the inclined surfaces adjacent to each other. ### Claim 9 (depends on 1) The conveying device of claim 1, wherein a length of each of the sliding surfaces is the same as a length of each of the inclined surfaces. ### Claim 10 (depends on 1) The conveying device of claim 1, wherein a number of the sliding surfaces is the same as a number of the inclined surfaces. ### Claim 11 (depends on 1) The conveying device of claim 1, wherein a length of the sliding surface of the treating area is longer than a length of the sliding surface of the preparation area. ### Claim 12 (depends on 1) The conveying device of claim 1, further comprising a discharge area in which an object to be conveyed treated in the treating area is conveyed, and in which one sliding surface and one restraining surface connected to each other, wherein a length of the sliding surface of the discharge area is longer than a length of the sliding surface of the preparation area. ### Claim 13 (depends on 1) The conveying device of claim 1, wherein a plurality of frames are provided, and the lifter and the drive unit have a number corresponding to a number of the frame. ### Claim 14 (depends on 1) The conveying device of claim 1, wherein the drive unit comprises: a linear motor which linearly moves in the first direction; and a mover which moves the lifter up and down by reciprocating in the first direction by the linear motor. ### Claim 15 (depends on 14) The conveying device of claim 14, wherein the mover comprises a moving surface inclined downward in the first direction, wherein the lifter comprises a guide surface which is in contact with at least a part of the moving surface and inclined downward in the first direction. ### Claim 16 (depends on 15) The conveying device of claim 15, further comprising a roller for reducing contact between the moving surface and the guide surface. ### Claim 17 (depends on 1) The conveying device of claim 1, wherein an object to be conveyed is lifted by the lifter on the one sliding surface and conveyed to the sliding surface of a next stage. ### Claim 18 A fabric treating apparatus comprising: a cabinet defining a treating chamber in which clothes is accommodated; a heating unit for supplying at least one of hot air and steam into the treating chamber; and a conveying device for conveying clothes positioned outside the cabinet to the inside of the cabinet, wherein the conveying device comprises: a frame comprising at least two sliding surfaces inclined downward in a first direction, and at least two restraining surfaces that is disposed between the two sliding surfaces and defines a surface intersecting the sliding surfaces; a lifter comprising at least two inclined surfaces inclined downward in the first direction, and at least two intersecting surfaces that is disposed between the two inclined surfaces and defines a surface intersecting the inclined surfaces;
